Battery Charger/Controller Lithium Capability?

[HappyKamper-JAY]

Does anyone know if the Battery Charger/Controller in 2020 Jayco Alante 29S is capable of charging Lithium Batteries?

I'm not an expert but here's what I've been reading as I'm looking at similar. Yes, it will charge lithium iron phosphate batteries but probably only to 80 to 90% capacity. They often don't have high enough voltage to fully charge and the float charge drops back down to 13.6V and is not enough.

That's not really the problem though, without a DC to DC charger those batteries pull a ton of unregulated amperage from your alternator and you will burn it up over time without a DC to DC charger. I think they can easily pull over 100A.

Thanks for your reply.

It depends on if your inverter/charger has a la-li switch. La = flooded or agm, li = lithium.
You'll also need to change your BIM to a Li-BIM to protect your alternator.

OK. Thanks for your input.

Thanks for your reply.

You can adjust the maximum current on the DC to DC chargers, or get a smaller DC to DC charger. ALSO STARTING IN ABOUT 2021 THE MAIN FUSE BOXES / INVERTERS BY PROGRESSIVE DYNAMICS starting adding a small circuit board switch to change the charge profile from LA to Li . Check your model inverter/fusebox/charger if you have a Progressive Dynamics unit.
